no.
nua_create()/nta_agent_create()/tport_bind() now joins to multicast group
if "maddr" parameter is specified.
this not applicable to our application. We don't have a proxy server or a
registrar server.
currently this is how we create the nua instance:
portPtr->sofiaStackPtr = nua_create(portPtr->eventLoopPtr,
EventCallback, // Event
handling callback func.
portPtr, // Additional
data to pass to callback.
TAG_END()); // ---- End of
tag list ----
we felt this was not needed to force a hard binding of the socket to a
local NIC address.:
NUTAG_URL(Address), // Local address to bind to.
if we do not recycle the stack, the nua stack nta layer will error out on
the transmission on a port that is no longer valid (because the address is
changed).

hence whether we specific a URL address for nua to bind to, or it picks a
loca address by default, I thought it wouldn't matter.

That *should* happen. however, the IP address change also means that
all the TCP connections and the UDP sockets bound to the old IP
address become useless. Do you include maddr= parameter in the
NUTAG_URL() in nua_create()?
